=I don't know, cheat=
Talk to him about and ask yourself if you really want to continue having a relationship with him.
Why would you want to change your relationship with him in the first place? If he is your best friend, you do NOT want to put that relationship in danger by just having him be a "friend with benefits" type of thing going on... What you could do is actually be boyfriend/girlfriend relationship which would still keep the friendship.
If you are a girl and you have a boyfriend.. Then the boyfriend will pressure you into having sex.
That's really up to you, but you can't have a serious relationship with someone below the age of about 13. If you are younger than that you can still have a boyfriend but they will really only be a boy that is just a friend.
in my uninformed opinion (i am a 15 year old guy), a boyfriend is one who will stay with his girlfriend through times of trouble, love her unconditionally, and remain a friend with her even if they break up. a boyfriend who just stays because of her looks is worthless in that relationship. you must love in order to be a boyfriend. ---- In my opinion if i have a boyfriend, that means (to me) that i will be there for him anytime he needs me!
You are not really being her best friend if you are having a relationship with her boyfriend. If they were broken up before your relationship then she has no right to be mad at you. But if they were still together then she has every right to be mad at you and you either break up with him and tell her you're sorry or stay with him and accept the fact that she probably will stay mad at you. My advice is that you break up with him and say sorry to her.
If he is having sex with her he is probably attracted to her.
Yes, it's dirty and cruel.
No.When I was 10,I had ton of friend who had an early relationship.UHEALTHY.Yeah as i say it.You are too young to have a relationship.Im sure SENSIBLE,SMART parents will say no.But there are THOSE of us who don't know how to raise children right.I say after collage would be better for you Yes, having a boyfriend at 10 is not like having a boyfriend and a relationship at 16.
If you care about your boyfriend, leave the old friend alone. If you are asking, you are probably too young to date just one person. Try not having a boyfriend and just have friends (and have fun).
The only way you can be positive your boyfriend is cheating is by having a friend take you in their car and follow him one night.
Maybe he is frustrated with having to deal with a long distance relationship. Visit him. That will change his mind.
